Benefits of technology

The present invention solves the problem of the unwanted cyan line defect in fold or crease lines in reflective color photographic elements (color prints). This is achieved by using a novel chemical composition in the interlayer between the red and green light sensitive color records, which is likely softer and more pliable in the resulting reflective color photographic element (color print) especially when it is folded or creased. The interlayer formulation can absorb any forces from the crease or fold that would normally rupture the cyan dye-containing silver halide emulsion layer, keeping it more intact. The improved interlayer reduces the cyan line defect compared to reflective color photographic elements absent the interlayer formulation. The interlayer formulation is not directed to color negative photographic elements that have multiple silver halide emulsion layers in each color record, which would not show the cyan line problem. The interlayer composition can be used in both interlayers, if necessary.

Problems solved by technology

This is an objection or “flaw” in otherwise high quality color photographic prints spread across the two open pages of a photobook.
It is believed that this problem is caused from the force of creasing, folding, and photobook making, which interacts with the series of light-sensitive layers in the color photographic element forming the color print.

Abstract

A color photographic element has a reflective support and a blue light sensitive color record, a green light sensitive color record, and a red light sensitive color record can be used to provide color photographic prints. The element also has a non-light sensitive interlayer between the green light and red light sensitive color records. This interlayer comprises a hydrophilic colloid and an acrylic latex polymer having a glass transition temperature (Tg) of less than 0° C. The presence of this acrylic latex polymer in the interlayer reduces the formation of a cyan line defect when the color photographic print is folded or creased, such as in photobooks.

Description

FIELD OF THE INVENTION[0001]This invention relates to silver halide color photographic elements that are useful as color photographic papers for providing positive photographic color images. The silver halide color photographic elements exhibit reduced appearance of colored lines or defects when they are folded or creased, for example when displayed in a photobook.BACKGROUND OF THE INVENTION[0002]The subtractive process of color formation is customarily employed in multi-colored photographic elements. The resulting yellow, magenta, and cyan image dyes are formed in silver halide layers that are sensitive to blue, green, and red radiation, respectively. It is known in the photographic art that these color images are customarily obtained by a coupling reaction between an oxidized aromatic primary amine developer and appropriate color-forming dye image forming color couplers.[0003]A typical silver halide color photographic element contains multiple layers of light-sensitive photographi...
